Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as the PMAT stages‚ which are the following: Prophase‚ Metaphase‚

cytoskeleton‚ responsible for cell shape‚ motility and attachment to other cells during interphase‚ disassemble Pro Metaphase: - nuclear envelope breaks down- no longer a recognizable nucleus. Mitotic spindle fibers elongate from the centrosomes and attach to kinetochores‚ protein bundles at the centromere region on the chromosomes where sister chromatids are joined Metaphase: Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell. Anaphase: Spindle fibers

Week 3 Team Reflection Summary MGT/230 Week two gave us an inside look on what the six steps are during the planning process. These steps are situational analysis‚ alternative goals and plans‚ goal and plan evaluation‚ goal and plan selection‚ implementation‚ and finally monitor and control. The step that Tina‚ Joanne‚ and Chris thought was most important in the planning process was the role of setting up alternative goals and plans. They believe it is always a good idea to have an alternative

hours of research I found the animal I wanted to do this assignment with‚ unfortunately in all the research I went over there was not one image of the internal structures of this animal. The animal I chose was the camel the image I found closest to what was asked for in this assignment is located at http://www.dragoart.com/tuts/13244/1/1/how-to-draw-camels.htm‚ a terrible site for scientific information but it is a good image with labels. The camel is an amazing animal that generally lives in dry

Meiosis is a type of cell division that is used for sexual reproduction. It creates the egg and the sperm cells. Meiosis begins with a parent cell (diploid)‚ which contains two copies of each chromosome. The cell then goes through DNA copying and two cycles of cell division‚ also known as Meiosis I and Meiosis II. When the cell goes through this cycle‚ it creates four haploid‚ which means they contain half of the number of chromosomes of the parent cell. Meiosis I begins with Prophase I. In Prophase

Prophase I D.N.A coils tightly and individual chromosomes become visible as single structures Homologous chromosomes become associated in synapsis. Each pair of chromosome is called a bivalent. Centrioles divide and move to the opposite poles of the cell‚ and spindles start to form Late Prophase I The bivalents duplicate to form tetrads (four-chromatid groups).The nuclear membrane disintegrates. Chromosomes join at points called chiasmata where crossing over takes place. Metaphase I The nuclear

arms concurs with the low cost strategy of BYD. Question 3 NO‚ because other nascent Chinese battery companies use only low cost strategy and they have no R&D department‚ the market is fragmented between them and there is no dominant company. Using both low cost and high quality (because of R&D department‚ vertical integration and using of manpower instead of robotic arms) allows BYD to be reliable and to dominate the market in China. Question 4 Yes‚ because Wang has both a short term and a
